Dataset: Citizen Complaints

Last Updated April 24, 2019

Please Note: The CPCO started using a new database and process for collecting this data in January 2014. Entries prior to January 2014 were entered into an older paper form, so they are unavailable in this dataset at this time.

Fields included in this dataset and their definitions:

Field	Information
Id	This is a hashed unique identifier for a given complaint. Complaints may contain multiple allegations. When that is the case, there will be multiple entries for one incident number.
Occurred Date	The date that the incident occurred.
Division	This is the Division that the officer was assigned to at time of the incident, such as Criminal Investigation or Administration.
District	This is the District, such as East District or NW District, or Branch, such as Homicide or Robbery, that the officer was assigned to at the time of the incident.
Shift	This is the shift, such as Day or Late shift, or section, such as crash investigation section, that the officer was assigned to at the time of the incident.
Beat	Some shifts contain this secondary level of detail on the officer's assignment.
Service Type	The reason for the interaction, such as Traffic Stop or Call for Service.
Source	Who received the complaint and whether it was categorized as formal or informal.
Allegation Type	Allegations in complaints fall into a number of classes. Some classes of allegations are: Citizen Interactions, Bias Based Policing and Use of Force.
Allegation	Allegations are tied to the regulations and standards which Officers are held to. Examples are: rude, demeaning and affronting language, and failure to provide name or badge number, which both fall under the allegation class of citizen interaction.
Finding	Each complaint may contain multiple allegations, such as rudeness and inappropriate language. Each allegation receives separate findings. There are four possible findings: Sustained means that the investigation agreed with the allegation in the complaint. When allegations are sustained, the Chief of Police will take the appropriate disciplinary action. Not sustained means that the investigation did not find evidence to prove or disprove the complaint. If allegations are found to be not sustained, the officer's name is submitted to IMPD's Early Warning system. Exonerated means the incident happened, but it was lawful and proper. Unfounded means that the incident happened, however not as detailed in the complaint. Complaints that are still being investigated will be blank in this column.
Resident Race	The resident's race, with the following categories: Asian, Bi-racial, Black, Hispanic, Unknown, White.
Resident Sex	The resident's gender.
Resident Age	The resident's age at the time of the incident, if known.
